Jack, rack type (without screws), manual with self-locking function, 50 kgf.
Faster and more efficient compared to screw jacks. It can be operated quickly and lightly by hand, has a compact design, and can hold loads without the need for a stopper, making it highly safe.
Unlike conventional screw jacks, this rack-type jack features an overwhelmingly fast rise and fall speed due to its high efficiency, making it easy to operate. It is also equipped with a unique self-locking mechanism that allows it to hold loads without brakes or stoppers, making it a groundbreaking jack. With a rated thrust load of 50 kgf, it can be operated manually with ease, advancing exactly 4 mm per rotation, which also makes it a round-number linear jack. Its significant advancement makes it a highly versatile rack jack and linear actuator.

The second volume of the case studies for the new self-locking deceleration mechanism "shoji-lock" has been completed.
- Small winches have been adopted in shops and museums in Ginza. = They have received positive feedback for their design, being compact and unobtrusive in black. = They are also praised for being easy to operate by ourselves, among other things. Instead of a worm gear, we have developed a completely new inline reducer that self-locks when motion stops, as well as a small winch that maintains position when the handle is stopped in both forward and reverse rotation instead of using a ratchet. Due to the positive reception and increased achievements in various fields, we have created a second edition this time. Please download it and consider it!

We will provide an explanatory booklet: Why does it stop? The secret of the new self-locking deceleration mechanism 'shoji-lock'
A completely new inline reducer that self-locks despite being a spur gear instead of a worm gear. Why does it self-lock? What is the internal structure like? We often get asked these questions. While showing a demo unit or a cut model can help people understand, such opportunities are rare. Therefore, we created a simple explanatory document. Please take a look at this, and if you're interested, feel free to check out our specific products and contact us.

The Ipros version of the S-Winch/S-Linear Actuator product catalog has been updated.
This is a completely new compact winch and rack jack that self-locks regardless of where it stops in forward or reverse rotation, not using a ratchet. It has received positive feedback from various sectors, and due to the increased lineup, we have renewed it this time. Please download it and consider it! Additionally, the comprehensive catalog featuring applied products such as those with motors is available for download from our company website. Please check it out as well.

New product information: A new modular type of self-locking rack jack has been introduced, featuring a rack movement of 17 mm with one rotation of the input shaft.
This is the second product that combines a modular jack with a gearbox featuring a new self-locking mechanism that does not use the conventional self-locking worm gear at all. The input shaft torque is light at 1.01 kgm at 100K, and a fast advancement of 17 mm per rotation has been achieved. We propose this to customers who want to lift quickly with minimal force and aim for space-saving in various factory production lines. Additionally, it is possible to attach guide rods (twin shaft type).

New Product Information: Jack 50KN Manual/Electric Rack Jack with Self-Locking Function
A jack that can lift a load of 50 kN with a light manual operating force (input shaft torque of approximately 11 Nm). This jack was developed for component maintenance as an application product of the new self-locking mechanism (Shoji Lock). The body weight is 36 kg and it is made of aluminum. It is designed with a focus on lightweight and manual operability. There are two input shafts (high/low), allowing for easy switching between quickly turning the handle when there is no load and applying force when a load is present simply by changing the insertion of the handle. It can be widely used for work in locations without power, as well as for disaster preparedness and energy-saving measures. It can also be used electrically.
